  • Patent number: 8408778
    Abstract: A display device including a light unit is provided. The light unit may include a light guide plate, a light emitting module, and a color coordinate conversion sheet. The light emitting module may include a plurality of light emitting diodes configured to emit light to a side of the light guide plate. The color coordinate conversion sheet may be positioned on the light guide plate to convert a color coordinate distribution of the light emitted by the light emitting module to a color coordinate distribution that falls within a target distribution range.
